A p well serving as a channel region of a MOSFET is formed on one side of an n⁻ layer and an n⁺ drain region is formed on the other side. Above the n⁻ layer, a plurality of first floating field plates are formed with a first insulating film interposed therebetween. A plurality of second floating field plates are formed thereon with a second insulating film interposed therebetween. Assuming that the thickness of the first insulating film is “a” and the distance between the first floating field plates and the second floating field plates in a direction of thickness of the second insulating film is “b”, a relation a>b is held.

A vehicle is provided with: an EPS a VGRS actuator as a rudder angle varying device; and an EPS actuator as a steering torque assisting device. In following a target driving route, a LKA target assist torque TLK is outputted from the EPS actuator on the basis of target lateral acceleration GYTG. On the other hand, in order to suppress the steering of a steering wheel by the assist torque, which is against a driver's will, steered wheels are steered by the VGRS actuator, excessively by a LKA correction target angle θLK. At this time, it does not influence a relation between a steering angle and the rotation angle of a lower steering shaft. Thus, the following for the target driving route is realized without reducing the robustness of the vehicle with respect to the driver's steering.

A traffic lane marking recognition apparatus includes a candidate detecting unit, a gap detecting unit, and a recognition reducing unit. The candidate detecting unit detects a lane dividing line candidate which is a candidate for a lane dividing line that defines a traffic lane on a road, based on an image of the road captured by an on-board camera that is mounted in a vehicle. The gap detecting unit detects a gap included in the lane dividing line candidate detected by the candidate detecting unit. When the gap is detected by the gap detecting unit, the recognition reducing unit reduces a probability of recognition of the lane dividing line candidate as a lane dividing line to a first probability that is lower than the probability when the gap detecting unit does not detect the gap, in a region from the gap closest to the vehicle towards a direction away from the vehicle.

An apparatus and method for suppressing dynamic instability in a bleed duct of a gas turbine engine includes a fan bypass duct configured to permit a flow of air through the gas turbine engine. The fan bypass duct defines a fan duct surface, and the bleed duct has an inlet in fluid communication with the fan bypass duct and a flow control valve having an opened position and a closed position. A flow diverter is positioned on the fan duct surface proximate the inlet of the bleed duct and diverts the flow of air from the inlet when the flow control valve is closed, while permitting a portion of the flow of air to enter the inlet when the flow control valve is opened.

A wind turbine-permanent magnet synchronous generator (WT-PMSG) system includes a variable speed permanent magnet synchronous generator and utilizes a static synchronous compensator (STATCOM) connected on the grid side of the system. A PI/PID controller is designed to apply modulation index control signals to the generator side-converter since the modulation index of the generator side-converter has been determined to have the higher controllability to damp the oscillatory modes of the system when the STATCOM is located at the grid side converter. The controller gains are tuned through a frequency based optimization procedure. This configuration dampens voltage instabilities to provide LVRT compliance.
